Easiest would be to replace what you have.. That engine bay looks huge, but look at a 61 Lincoln engine compartment with engine installed... not a lot of daylight there. There are plenty of rusty Lincolns out there that run. I would search for an original.. Lincoln changed bell housings 2 times in this series, mostly because of clearance issues.. a later 460/c/6 would run into clearance issues if you want to keep the AC and heater .. Also these have windshield wipers operated by the power steering pump so a regular remote mounted pump probably does not have the capacity to run steering and wipers at the same time
